 It was the only Export to be named "Mille Miglia" by the factory and the only to sport an "M" in its chassis number suffix.The biggest difference over the succeeding examples of the series was the carburettors setup, made up of triple four-barrel Webers.In April 1952, just before Mille Miglia race, the car received an updated new bodywork, still in Vignale Berlinetta form, with recessed grille and had portholes in fenders installed before Le Mans.
